Overlay material for plain bearing

摘要

A lead-free multilayer material for plain bearings and a process for the production of corresponding bearing shells for improved emergency running and mechanical load-carrying capacity characteristics. The multilayer bearing material comprises a lead-free copper alloy having a copper content ranging from 50 to 95 wt. %, and an overlay formed of a lead-free tin and copper having a tin content ranging from 70 to 97 wt. % and a copper content ranging from 3 to 20 wt. %.
